Phone Microphone Works in Calls but Not Apps? Fix It

On Android, menu names vary by maker, so use Settings search when a path in a guide does not match your phone exactly.

Start by narrowing the cause

• the wrong microphone/input device is selected
• microphone permission is denied for one app
• Bluetooth or USB audio routing is taking the input
• debris or a case is blocking a microphone opening
• the microphone works in one mode but a specific app has a configuration problem

Work through these checks

1. Record a short voice memo or system test outside the affected app.
2. Check microphone permission for that app.
3. Disconnect Bluetooth/USB audio and retest the built-in microphone.
4. Inspect microphone openings without inserting sharp tools.
5. On Windows, confirm the correct input device in Sound settings.

Isolate the failing layer

Record audio with a system recorder, then test the failing app. A clean system recording with a bad app recording points toward permission, routing or app configuration—not a dead microphone.

Use the same app, output device and audio clip for each check. Switch only one permission or audio route at a time.

What not to change first

Confirm that the problem is actually gone

Compare a system recording with the failing app; that tells you whether the fault is app-specific or system-wide.

When to use support or repair

If one accessory fails with multiple hosts, contact its maker; if several accessories fail in one app, report the app version and audio route.

Record accessory and host model, app/version, selected microphone/output and whether another app works. Hide account identifiers.
